I want to get the type of element, that I've got selected using jQuery selectors.
Markup:
<select name="a"></select>
<input name="b" type="text" />
<textarea name="c"></textarea>
J开发者_开发技巧avascript:
var field_names = new Array(
'a',
'b',
'c'
);
for(var i = 0; i < field_names.length; i++) {
var field = $('[name=' + required_fields[i] + ']:visible');
// ?????
// What do I write here to get one of those outputs:
// Element with name a is <select>
// Element with name b is <input>
// Element with name c is <textarea>
alert('Element with name ' + required_fields[i] + ' is ' + element_type);
}
Use the DOM element's tagName
property:
var element_type = field[0].tagName;
Note that browsers are not entirely consistent about the case returned by tagName
, so you should probably call toLowerCase
to be safe: field[0].tagName.toLowerCase()
.
Simple:
var element_type = '<' + field.get(0).tagName.toLowerCase() + '>';
In a nutshell, this retrieves the DOM element associated with field
and gets its tag name via the tagName
attribute inherited from DOMElement
, then transforms the result to lowercase using String
's toLowerCase()
method. Some browsers will return the tagName
in uppercase, so for consistency you should transform it to lower case.
